CareerPuerta made his debut on the ATP Tour in 1996. He won his first ATP title in 1998 in Palermo, Italy. In 2000 he reached what most consider the peak of his career, making it to five finals, and winning one of them (Bogotá). That same year, however, he underwent wrist surgery, which kept him off the circuit for several months.Besides not recovering his previous playing level, in 2004 he was sanctioned for 9 months for a doping offense (see section on doping controversies). Owing to the suspension he missed most of the 2004 season, and by August 2004 his world ranking had dropped to 440. He was reduced to playing Challenger-level tournaments for a while until he had earned enough points to return to the ATP Tour.In 2005 Puerta made an eye-opening comeback on the Tour by winning the title in Casablanca and then making it to the final of the world's most prestigious clay court tournament, the French Open, where he eventually succumbed to Rafael Nadal in a close match (7–6(6), 1–6, 3–6, 5–7). By August 2005 he had climbed to a career-best 9th place in the ATP entry rankings, an advancement of 431 places in one year.In December 2005 he was, again, suspended for a doping offense, this time for 8 years, effectively ending his professional career. This suspension was later reduced on appeal.Puerta is left-handed and uses a one-handed backhand. He is a clay court specialist with a game that revolves around groundstrokes with heavy topspin. On fast surfaces his game is compromised by his comparatively weak serve and slow court speed. His three ATP titles so far were all won on clay.

The suspension was for 8 years, the longest so far in tennis history. Puerta also had his results disqualified from every event from the 2005 French Open onwards, and forfeited all his entry ranking points and prize money. Since he had recently lost the French Open final to Spain's Rafael Nadal, that signified a loss of €443,282 (£300,671, $456,000).

Puerta appealed against the ban, claiming on his web site that he only ingested trace amounts of it accidentally left over by his wife in a glass.

On July 12, 2006 his suspension was reduced to 2 years by the Court of Arbitration for Sport, making him eligible to restart his career on June 5th 2007.

ComebackOn June 6, Puerta returned to the professional circuit with a 6–4 6–3 victory over Australian Joseph Sirianni at the Sassuolo Challenger, a tournament to which he was invited as a wild card since he had no ranking[2]. In the second round, Puerta lost 6–3 6–0 to Spaniard Marc Lopez. Since returning to the ATP, Puerta has only played on the ITF circuit, reaching the quarterfinals of the Trani and Puebla challengers, the semifinals of the Belo Horizonte and Medellin challengers, and the final of the Cordenons challenger. Since returning to the tour, Puerta has notched wins over such top 200 players as Fabio Fognini, Marcos Daniel, Christophe Rochus, and Frederico Gil and amassed a 21-17 singles record and 0–1 doubles record in 2007 (including 3 wins in qualifying)2008 has been a semi-successful year so far with Puerta raising his ranking to 151, on July 13th.
